Instability of standing waves for the Klein-Gordon-Schrödinger system.
Hokkaido Mathematical Journal, 37 (2008) pp.735-748
We study the orbital instability of standing wave solutions for the Klein-Gordon-Schrödinger system in three space dimensions. It is proved that the standing wave is unstable if the frequency is sufficiently small.
